No matter how funny, heartwarming, or awesome the Dresden 'verse can be, it's still a very dark place that will always gutpunch you right in the feelings.
[[AC: Short stories]]
* The end of the short story 'Love Hurts", when Harry and Murphy realize they have to end the spell and go back to the way things were.
* A subtle but very, very dark one in ''Backup'': Thomas confronts the Stygian at the end, and, while horribly poisoned, he [[spoiler: rapes her and feeds her to his Hunger, killing her and letting his Hunger fight off the poison to keep him alive.]] The worst part is how simple and understated the scene is. Thomas has been fighting his demon for so long, working to not abuse others around him, but is forced by both the poison and his enemy to [[spoiler: consume her life force]]. It is dark and subtle and quiet and ''incredibly'' tragic.
* In ''Cold Case,'' Molly, just beginning her role as the Winter Lady, and Carlos develop a budding romance, and even start to have sex. She wakes up [[spoiler: in the shower with blood all over her hands, and Mab explains that due to her being the Winter Lady and thus the maiden of TheHecateSisters, the mantle reacted automatically and brutally hurt Carlos, as it will anyone with whom Molly tries to have sex with.]]
* The flashback images of young Harry from ''Ghoul Goblin'' are pretty touching, the moreso when you think about how long those experiences (finding his father dead, having killed Justin) are going to haunt and isolate him.
